Sony says the zoom is the first Sony alpha E-mount lens to reach 300 mm and features high resolution and excellent overall optical performance throughout the entirety of its range. The 50 mm prime lens is extremely compact and lightweight, says the company.

The 70-300 mm lens features a state-of-the-art optical design, Sony explains, including four aspherical glass elements, two ED (Extra-low Dispersion) glass elements and Sony’s Nano AR coating, all of which are said to work together to effectively suppress spherical aberration, distortion, and chromatic aberration.

The zoom has a minimum focusing distance of less than 3 feet (0.9 m) and a maximum magnification of 0.31x, and is said to display excellent corner-to-corner sharpness.

The lens includes built-in Optical SteadyShot image stabilization and a linear actuator that allows it to achieve fast, smooth and quiet autofocus, and is also dust and moisture resistant.

50 mm

Weighing less than 7 oz (192 g), the new lightweight 50 mm prime lens features a new optical design with an aspherical element that effectively compensates for all forms of aberration, says Sony, resulting in beautiful, crisp imagery. Additionally, it has a circular aperture producing beautiful ‘bokeh.’

The new prime lens is built with a solid metal mount.

The Sony FE 70-300 mm f/4.5 – 5.6 G OSS telephoto zoom lens will be available in May for about $1,700.

The FE 50 mm f/1.8 prime lens will also be available in May for about $350.
